LIQUID-MEASURE.

EBPECIFKCATION forming part of Letters Patent No. 325,265, dated September 1, 1885.

Applicati n filed April 6, 1885. (No model.)

T0 or whom it may concern.-

Be it known that we, \VILLIAM MITTEN- DORF and JOHN H. Mirrnunonr, both citizens of the United States, and residing at Dayton, in the county of Montgomery and State of Ohio, have jointly invented certain new and useful Improvements in Liquid-Measures, of which the following is a specification.

Our invention relates to that class of liquid measures in which the liquid to be measured is drawn from the main reservoir into the measuring-can proper, and thence into the can or other vessel in which the measured liquid is to be delivered.

WVe are aware that a great variety of meats uring-cans of the general type above referred to have been devised and offered to the publie; but most, if not all, of these are objectionable on account of the number of stopcocks or faucets used and the danger that by neglecting to properly adjust all of the faucets the liquid may be permitted to flow into the nieasnringcan by the inletpipe while it is being withdrawn therefrom by the exitpipe, or the liquid may be withdrawn from the measuring-can beforeit has been properly filled, thus giving rise to errors. They are also objectionable for the reason that no provision is made to prevent dripping after the exitcock is closed.

The object of our invention is to provide a measuring-can which renders it impossible for the attendant to make such errors, insures accuracy of measurement, and provides against dripping; and it consists in the details of construction hereinafter described and claimed.

In the drawings, Figure 1 is aside elevation of a liquid-measure embodying our invention. Fig. 2 is a front view of a portion of the same; Fig. 3, a longitudinal section of a two-way cock in position to allow the liquid to flow from the reservoir into the measuringcan. Fig. 4 is a crosssection on the line 4 4 of Fig. 3; Fig. 5, a longitudinal section of the cock, shown in position to allow the liquid to flow from the measuring-can to the receiving-vessel; and Fig. 6, a cross-section on the line 6 6 of Fig. 5.

A represents a reservoir, and B a measuring-can connected with A by a suitable pipe, a. In order that the attendant may readily see the height to which the liquid extends, the measuring-can is provided with a section, b, of glass or other transparent material, preferably of semi-tubular form, wit-h the convex surface thereof projecting from the surface of the can. Either upon or immediately adjacent to this glass section is a gage, b. It preferred, the entire measuring-vessel may be of glass and the gage placed upon its surface. An air pipe or vent, b, connects the interior of the can 13 with the air, and extends slightly above the top of the reservoir A in order to prevent overflow. To prevent liability of breakage, we prefer to pass this pipe through the interior of the reservoir A.

O is a cock having a spout, c, the heel c of which constitutes a valve oscillating in a sleeve, 0'. In the valve portion of the spout is a port, 0, and the exterior surface of c is cut away, leaving a space, 0, which serves as a passage for the liquid. In the sleeve are ports 0 and 0", connecting, respectively, with the reservoir A and the measuring-can B.

The operation is as follows: The spout being in the position shown in Fig. 3, the passage c connects the ports a and 0', allowing the liquid to flow from the reservoir A into the measuring-can B. hen a portion of the liquid is to be measured for sale or use, the spout is turned to the position shown in Fig. 5, closing the passage 0 and opening the port 0, as shown in Fig. 6, allowing the liquid to flow from the measuring can through the spout into the receivingvessel. \Vhen the gage indicates that the desired quantity has been drawn off, the spout is again reversed and the liquid is again free to flow from the reservoir into the measuring-can, while the drippings are held in the spout instead of falling to the floor. The ports are so placed that the passage is entirely closed before the port- 0 begins to open.

\Ve claim as our invention- In a liquid-measure, the combination of the reservoir A, the measuring-can 13, provided with window I) and gage Z), the vent b, and pipe a, with the reversible cock 0, consisting of spout 0, having port 0 and passage 0, oscillating in the sleeve 0 having ports 0 and a", substantially as and for the purpose specified.
